Using caffeine to make up for lack of sleep creates a vicious cycle. Here’s how it works: you drink caffeinated beverages because you didn’t sleep enough last night. But the caffeine keeps you from falling asleep the next night, shortening the time you sleep. Caffeine can disrupt deep sleep so you wake up more times during the night and feel less rested in the morning. You wake up tired the next day and reach for your morning jolt of caffeine and the cycle starts again.
Cutting back on caffeine can help you sleep better and have more energy in the long run.
